A former Maine man has been convicted of bashing his wife's head with a rock and pushing her off a cliff in disputes over an affair and inheritance money.

The couple, Charles and Lisa Black, had moved from Kansas to retire in coastal Maine. Before the fall in 2011, they'd argued about how he spent money from a $4 million inheritance from her father and over an affair he had.

Prosecutors say 71-year-old Charles Black hit his wife with a rock before pushing her off Maiden Cliff. Both tumbled down the mountainside.

He was found guilty Monday of attempted murder and other charges.

Charles Black, who now lives in Utah, did not testify. He has said he had no memory of pushing his wife. They have divorced, and she goes by Lisa Zahn.

Both Black and Zahn are former employees at schools in Johnson County, Kansas.
